Three-dimensional simulations of the interaction between type Ia supernova ejecta and their main sequence companions [PDF]
, 2012 Context. The identity of the progenitor systems of Type Ia supernovae (SNe Ia) is still uncertain. In the single-degenerate scenario, the interaction between the supernova blast wave and the outer layers of a main sequence companion star strips off ...

Accretion and outflow activity on the late phases of pre-main-sequence evolution - The case of RZ Piscium [PDF]
, 2017 RZ Psc is an isolated high-latitude post-T Tauri star that demonstrates a UX Ori-type photometric activity. The star shows very weak spectroscopic signatures of accretion, but at the same time possesses the unusual footprints of the wind in Na i D lines.

Winds in Star Clusters Drive Kolmogorov Turbulence [PDF]
Astrophysical Journal, 2020 Intermediate and massive stars drive fast and powerful isotropic winds that interact with the winds of nearby stars in star clusters and the surrounding interstellar medium (ISM).

The impact of type Ia supernovae on main sequence binary companions [PDF]
, 2008 Context. The nature of type Ia supernova progenitors is still unclear. The outstanding characteristic of the single-degenerate scenario is that it contains hydrogen in the binary companion of the exploding white dwarf star, which, if mixed into the ...

A New Catalog of Am-type Chemically Peculiar Stars Based on LAMOST
The Astrophysical Journal Supplement Series, 2023 A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data Releases 8 (v1.0), 9 (v0), and 10 (v0), which greatly expands the database

Magnetic Activity of F-, G-, and K-type Stars in the LAMOST-Kepler Field [PDF]
ApJS,247,2020,9, 2020 Monitoring chromospheric and photospheric indexes of magnetic activity can provide valuable information, especially the interaction between different parts of the atmosphere and their response to magnetic fields. We extract chromospheric indexes, S and Rhk+, for 59,816 stars from LAMOST spectra in the LAMOST-Kepler program, and photospheric index, Reff,
